She explained what she was about to do and proceded to repair crack
In no time she was finished and removed equipment and cleaned windshield after repair.
After she had left when I got in truck to move I noticed that there were still several cracks coming out of all directions of where the original crack was.
I may misunderstand the repair process but I thought the materials injected in the crack filled all the voids in the glass.
I'm Ok with what it looks like provided in the future the hair line cracks I see don't spread through the whole windshield
